The Shangri-Las were a girl band in the 60's who had a reputation as tiny lady badasses, one of them was arrested for carrying a firearm over state boundaries, and they sung songs about boys on motorbikes and other things thats parents wouldn't approve of. They were pretty revolutionary for their time, some would even say they were the earliest example of punk and the metal band Twisted Sister hails Leader of the Pack as the originating the metal aesthetic. In interviews they say that they had to maintain the reputation so that when they were on tour all the men they would surrounded by would leave them alone (they toured the country as teenagers), so they seem like cool ladies and their albums all feature them looking like the kind of gang girls want to be a part of.
Why haven't I looked at glam-rock before I have no idea, probably because it's a little bit too cheesy and 70's for me, but New York Dolls are sort of proto-punk pre-glam explosion going pretty much for shock value and still super cool and not sliding embarrassingly into three-quarter-life crises. They're pretty much the classic rock band, too much for most record producers, critically acclaimed with a cult following but basically unpopular in the majority. The album is actually great, and the cover is basically exactly what I want to achieve, they all look proper thuggish and scary, but also definitely feminine. It's a hard balance to strike because most connotations of femininity are the exact opposite of the masculine aura of authority, cos y'know. Patriarchy.
